"We did not make an assessment of the impact that Russian activities had on the outcome of the 2016 election. The US Intelligence Community is charged with monitoring and assessing the intentions, capabilities, and actions of foreign actors; it does not analyze US political processes or US public opinion,” the report said.

But Feinstein, the ranking member of the Intelligence Committee, said "I do. I believe that" Russia's interference altered the outcome of the election.

In a closed briefing Friday, former Democratic National Committee (DNC) chairwoman Rep. Debbie Wasserman Schultz (D-Fla.), who was forced to resign last summer as head of the DNC amid the hacking scandal, confronted Comey over his handling of the organization infiltration.

Feinstein said Sunday that she was not prepared to say Comey should be fired.

“Not yet,” she said, when pressed by NBC’s Chuck Todd.

"I think the inspector general's report [into the investigation] is critical in this. Because there are rumors of all kinds of conflicts within the FBI that focused on the director. The director, I think, was torn."

"I think he did what he thought was right," she said, adding, "In my view, it turned out very much not to be right."
